Multiplying by 2 then dividing by 3 is the same as multiplying by 2/3 as you also divide by 3, but in one step.
Hope this helps!
Answer:
For every 5 female birds in the pet store, there are 3 male birds.
Step-by-step explanation:
Ratios are used to represent a proportion. In this case, we are comparing female and male birds. So, since female is 5 and male is 3, the ratio is 5:3
The right answer for the question that is being asked and shown above is that: "d.8 open parentheses x plus 4 close parentheses over quantity x minus 6" The simplified that completely quantity 8 x minus 56 over quantity x squared minus 49 divided by quantity x minus 6 over quantity x squared plus 11 x plus 28 is that <span>8 open parentheses x plus 4 close parentheses over quantity x minus 6</span>
Answer:
The number of newborns who weighed between 1614 grams and 5182 grams was of 586.
Step-by-step explanation:
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The mean weight was 3398 grams with a standard deviation of 892 grams.
This means that 
Proportion that weighed between 1614 and 5182 grams:
p-value of Z when X = 5182 subtracted by the p-value of Z when X = 1614.
X = 5182



has a p-value of 0.9772
X = 1614



has a p-value of 0.0228
0.9772 - 0.0228 = 0.9544.
Out of 614 babies:
0.9544*614 = 586
The number of newborns who weighed between 1614 grams and 5182 grams was of 586.
